摘要
,一共有3层可采煤层,分别为23#、30#、36#, 煤层总厚度为6m。煤层工业牌号为1/3焦煤,,。,煤层平均倾角为12°,属于缓倾斜煤层。
本矿井设计采用以立井为主的综合开拓方式,划分为两个水平,八个带区,两个采区。本着“节约优先,效率为本”的原则,本矿井设计中设计,一个工作面达产,达产时带区个数为一个。开采顺序一次为23#、30#、36#。采用集中布置,23#、30#、36#层集中开采。大巷运输采用10t架线式电机车牵引3t底卸式矿车运输,一水平采用的采煤方法为倾斜长壁采煤法,二水平采用的采煤方法为走向长壁采煤法,采用的采煤工艺为综合机械化采煤工艺。顶板处理方法为全部跨落法。
关键词:倾斜长壁采煤法; 走向长壁采煤法; 全部跨落法
Abstract
The Mine Design is a shaft design JiXi HaDa Mine Mt /a, The mine has three minable Coal Seam, consisting 23#,30#,36# seam and its average thickness is 6m. Industrial brands are one third, designed field of minable capacity is Mt ,it can adapt for . Average alignment in farmland in shaft lengthway average slant lengthways average rake angle in coal seam 12°, belong to the slant the coal seam.
The mine design is applied indined shalt development method, and is divided into two levels, eight mining adopts and two mining spirit of "giving priority to efficiency-oriented" principle, the synthesis mechanization ming coal ang one worked faces. Centralizing layoutis23#,30#,36#. Mining sequence for a 23#,30#,36#. Roadway transport using 10t overhead line electric traction 3t-bottom tub transport, a level of the mining method used for inclined longwall mining method, the two levels of the mining method to long wall mining, the mining technique for integrated mechanized mining technique. Roof approach for the entire cross-loading method.
Keywords: Inclined longwall mining method; Longwall mining method; All inter-drop method
